A delightful dessert featuring tender apples topped with a crunchy walnut crumble.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
In a mixing bowl, combine the flour, brown sugar, walnuts, oats, baking powder, and cinnamon.
Mix thoroughly to ensure the topping is evenly flavored.
Cut the butter into the dry mixture using a pastry cutter until it resembles coarse crumbs.
Cold butter works best for a crumbly texture.
Peel, core, and slice the apples.
Use a mix of apple varieties for a more complex flavor.
Arrange the apple slices in a buttered 9x13 baking dish.
Layer the apples evenly for consistent baking.
Sprinkle the sugar, cinnamon, and lemon juice over the apples.
Adjust the sugar to taste based on the sweetness of the apples.
Spread the prepared topping evenly over the apples.
Press the topping gently to ensure it adheres to the apples.
Bake in the preheated oven for 45 minutes, or until the topping is golden brown and the apples are tender.
Check halfway through to ensure even baking.
Let cool slightly before serving warm with whipped cream or ice cream.
Allowing it to cool slightly enhances the flavors.
